Gradient= (y2-y1)÷(x2-x1)
= (-2-7)÷(2+1)
= -3
Subt the gradient into one coordinate point (2,-2)
Let 2 be x, -2 be y
Equation of line = y=mx+c
-2= -3(2) + C
therfore C is 4.
Equation of line is y=-3x+4

12.4 / 6.2 = 2
so other side of enlarged rectangle = 1.8 x 2 = 3.6
Perimeter of enlarged rectangle = 2(3.6 + 12.4) = 32
Answer: 32 feet
------------------------
Another way to do:
12.4 / 6.2 = 2
SF = 2
The original rectangle has a perimeter of 16
Perimeter of the enlarged rectangle = 16 x 2 = 32
Answer: 32 feet
